Specifically, after the user searches for the WIFI hotspot with the corresponding name, click Connect and enter the password to connect to the desired WIFI hotspot; of course, there are also some public places that do not need a password when connecting.

Most mobile phones now have the function of remembering WIFI hotspots. In other words, after connecting to a WIFI hotspot, if you connect again later, as long as the name and password of the WIFI hotspot have not been changed, it will automatically connect without entering a password. Such a function will allow the mobile phone to automatically connect as long as it turns on the wireless and stays in the coverage area of the WIFI hotspot.

Embodiment two

In this embodiment, on the basis of Embodiment 1, a WIFI router and a mobile phone are taken as examples to describe in detail how a terminal accesses a wireless network through an access point.

In actual application, the WIFI router in this embodiment is a programmable WIFI router, so that the solution of this embodiment can be realized.

The password setting method described in this embodiment includes a router end and a mobile phone client end. Specifically, set the WIFI password on the router side through an encryption algorithm, so that the password corresponds to the date of the day; and then transplant this encryption algorithm to the client development, so that the only client also has the same password, so that Match with the router side, so that the user can only connect to WIFI through the mobile phone client.

First, describe the process of setting a password on the router side, as shown in Figure 3, the process includes the following steps:

Step 301: Obtain the current time;

Here, the machine time exists in the router, and the current time can be obtained by reading the machine time.

Step 302: intercept the year, month, and day of the current time as the current date;

Here, after intercepting the year, month, and day of the current time, it is converted into a YYMMDD format for use when generating a password.

Step 303: Generate a password required to access the wireless network;

Specifically, according to the known date YYMMDD and the router ID, pass these two character strings through an encryption algorithm and a known key to generate the required password.

For example, if the router is set on the No. 214 bus, the router ID can be set to gj214. At this time, the two strings of the known date YYMMDD and gj214 are passed through the encryption algorithm and the known key. Generate a passphrase as the passphrase required to access the wireless network.

Step 304: Set the generated password on the router.

Here, the router ID is set on the router at the same time, so that the router saves the generated password, so that when the user accesses through the mobile phone later, the legitimacy of the user can be verified.

Next, describe the process of the mobile client generating a password and accessing the wireless network through a router, as shown in Figure 4, the process includes the following steps:

Step 401: the user opens the client on the mobile phone and searches for WIFI hotspots;

Specifically, after the user opens the client terminal on the mobile phone, the client terminal will search for all surrounding hotspots, that is, WIFI routers.

Step 402: Judging whether the searched WIFI hotspot has a hotspot with a specified identifier, if yes, execute step 403, otherwise, execute step 401;

Here, the client compares all the hotspots in the surrounding area, selects the hotspot with the specified ID, and displays the currently searched list of available WIFI hotspots, that is, displays the ID of the hotspot with the specified ID. The hotspot ID displayed by the client has been preset.

Step 403: Receive the instruction of the hotspot selected by the user;

Here, the user selects the hotspot to be connected from the hotspot IDs displayed on the client and clicks to connect.

Step 404: Obtain the current time of the client;

Step 405: Intercept the year, month, and day of the current time to obtain the current date;

Here, the obtained current date needs to be sorted into the time format YYMMDD corresponding to the router, so as to generate the password required for accessing the wireless network.

Step 406: According to the obtained current date and the router ID of the hotspot selected by the user, generate a password required for accessing the wireless network through an encryption algorithm;

Here, the acquired current date and the router ID are passed through the same encryption algorithm and known key as the router to generate a password. And this password should match the password of the specified router.

By considering the time stamp, that is, the current date, the dynamic setting of the password is realized, so that the password of the router is different every day.

After getting the password and hotspot ID, you can connect your phone to WIFI.

Step 407: The mobile client sends an access request carrying a generated password to the WIFI router corresponding to the hotspot ID selected by the user;

Here, the WIFI router matches the password stored by itself with the password carried in the access request. If the match is successful, the connection is successful, and if the match fails, the connection is not allowed.

The password saved by the WIFI router is a password formed based on its own current date, that is, the WIFI router obtains its own current date, and generates a password based on the date and router ID through an encryption algorithm; among them, the router ID has been set in advance.

After the connection is successful, the mobile terminal can connect to the router and use the network resources shared by the router.

So far, the user's operation process is completed, the user's operation is simple, and the security of the user's login to the router is greatly improved.

In addition, the password generated by the client is consistent with the password of the router to complete the connection, and the client is also the only way to connect to the router, which also ensures security.

As can be seen from the above description, the scheme of this embodiment is used to set the password through the programmable router combined with the current date, so that the password changes with time. The password of WIFI is changing every day, so it will not Automatically connect every day, which means that users will open the client connection every day to increase the activity of the client. Users will not automatically connect when they do not need to use the network, saving resources. Only when the password generated by the client is consistent with the password of the router can the connection be completed, that is to say, the connection password of the client will also change accordingly, making the client the only way to connect to the hotspot, which can enhance the login security; and this way Through the client, users can also be managed in a unified manner, so as to understand the user's behavior and habits.
